Overboosting Problem???

[Unscarred711]

I have a Apex i avc-r controler and even with the boost controler OFF and runing just of the wastegate it is pulling up to 1.7 bar. Idearly i would have it at around 1 bar.

Also i have an Apex i comp and when i look at the Knock level sensor it has reached up 94. Is that considered a bad knock??

Since the boost controler is off why is is boosting up so hard and how do i stop it before somthing major goes wrong??

Turbo is a HKS 25/30 with an external wastegate.

any help would be great. Thanks

turbo is a GT35 tho.. with 48mm progate (i think thats the wastegate cant member)

problem might be if its a turbosmart wastegate.. not EBC that we have tried has worked with turbosmart wastegates.. how ever those cheap lil tboost's work fine
